    摘要: A preboot execution environment (PXE) test device includes a microprocessor, one or more indicators, a network interface, a power connector, and a storage device. The network interface connects the PXE test device with a computer. The power connector connects an external power source to supply a voltage to the PXE test device. The storage device stores a boot loader, an embedded operating system, and one or more programs. The microprocessor executes the boot loader and the embedded operating system to start the PXE test device. The one or more indicators indicate a power supply status and a starting status of the PXE test device. The microprocessor further executes the one or more programs to remotely boot the computer for test PXE of a network card in the computer.

    摘要: In a system and method for testing a serial port of a computing device, the serial port electronically connects to a test fixture. Test data is sent to a receive data (RXD) pin by a transmit data (TXD) pin. A test result is received from the serial port by the RXD pin. The TXD pin and the RXD pin work normally if the test data is identical to the test result. When voltages of a request to send (RTS) pin and a data terminal ready (DTR) pin are set at high level, the RTS pin, a data carrier detect (DCD) pin, the DTR pin, a ring indicator (RI) pin, a data send ready (DSR) pin and a clear to send (CTS) pin work normally, upon the condition that status values of the serial port indicate the voltages of the above six pins are at high level.

    摘要: A display apparatus includes a photoelectric sensor disposed on an inner side of a frame and located corresponding to a corner of a pixel area of a display panel in a predetermined position. When the display apparatus is turned on, the display panel provides a light spot at a corner of a current pixel area of the display apparatus corresponding to the photoelectric sensor, and a micro-control circuit compares an electronic signal received from the photoelectric sensor with a sample value. If different, an interrupt is triggered to execute a position offsetting interrupt program to adjust the display parameter of the display apparatus, thereby moving the pixel area to adjust the relative position of the light spot and the photoelectric sensor, so that the relative position becomes identical to that when the pixel area of the display panel is in the predetermined position.

    摘要: In a method for controlling a screen protection function of a portable electronic device, the portable electronic device includes a gravity sensor, a display screen, and a storage system. The gravity sensor detects a horizontal vector and a vertical vector of a gravitational acceleration of the portable electronic device, and a tilt angle of the portable electronic device is calculated according to the horizontal vector and the vertical vector. The method activates a screen protection program of the portable electronic device to control the display screen to enter into a power saving mode if the tilt angle exceeds a preset tilt angle range stored in the storage system, and terminates the screen protection program to control the display screen to enter into a normal display mode if the tilt angle does not exceed the preset tilt angle range.
